He was diagnosed with the disease, which strikes one out of every seven men, after a routine checkup and underwent treatment as he continued his duties as governor.

Spokesman J.J. Abbott said Wednesday that Wolf went to a follow-up appointment with his doctor last week and "he has a clean bill of health." Abbott said it's his understanding that that means the governor is now cancer-free.

Gov. Tom Wolf has received a "clean bill of health" following his battle with prostate cancer last year.

At the time the diagnosis was announced last February, the now 68-year-old governor encouraged Pennsylvanians to schedule regular checkups and follow screening guidelines for early detection.

According to the American Cancer Society, roughly 161,000 new cases of prostate cancer are expected in 2017 with about three-fifths of those cases being men aged 65 or older. One in 39 men will die of prostate cancer.

Earlier this week, another Democratic governor--Mark Dayton of Minnesota--announced that he would be undergoing radiation and surgery for prostate cancer. On Monday, he collapsed while giving a state of the state address.

"If I had known it would result in Republicans not criticizing my speech, I might have tried it years ago," Dayton joked, at a later press conference.
